Description
STOD2540 is dedicated to Passive Matrix OLED
(PMOLED) displays for portable handsets and
provides the pre-charge and biasing voltage of
the column matrix driver as shown in Figure 3.
The current capability of STOD2540 allows
feeding a 1", 1.3" or 1.5" color PMOLED.
STOD2540 is a boost converter that operates
from 3.0V to 5.5V and can provide an output
voltage as high as 25V. The output current
capability is maximum 40mA up to 25V output
voltage. The regulation is performed by a resistor
divider network (
Figure 3.
) that detects the output
voltage.
In this state-of-the-art boost converter, a DC
current path exists between the battery source
and the load. In order to reduce the consumption
in Shutdown mode, a high-side load isolation
switch is necessary to cut this DC current path in
Standby mode. The Load Disconnect Switch
(LDS) actsas an isolation switch in Shutdown
mode.
